hahahaha yes the difference is extremely minimal for the studs, and not a problem. I do have a set of cop wheels here with a pretty aggressive light truck tire tread on my camper van, maybe I will just use those.

I have opened a can of worms here anyhow, pedal was solid, and you could see the calipers appeared seized...pretty bad. So I wheeled it in, pulled it all as I had pads and calipers in the basement... figured I want good brakes on a winter car...swapped them, but it is still stuck when I went to bleed. pushed hard, bang, to the floor and no return. UGH. M/C maybe? I have a new one here. going to see when I have an assistant in an hour or so. Going to look at the rears while I wait.
